Latters
Flannery O’Connor has provided this plural form of the adjective “latter.” It occurs in A Good Man Is Hard to Find, in a statement referring to the character known as the Misfit:
“My daddy said I was a different breed of dog from my brothers and sisters. ‘You know,’ Daddy said, ‘it’s some that can live their whole life out without asking about it and it’s others has to know why it is, and this boy is one of the latters. He’s going to be into everything!'”
